Hello all ... first time poster here .....
I have a 2001 Grand AM w/ 3400. A few weeks back it started to intermittenly loose the signal from the MAP sensor to the PCM. Now it has lost it all together. It has 5 volts going into and a reference voltage coming out but its not reaching the PCM.
I need to find out which pin it is at the PCM along with any other information in regards to this anyone has to share.
Thanks,
Duane
